Anything relevant I should know about the Hastings manor? I've made a few assumptions so far. Are the lights electric yet or are we still flame-powered? My baseline is the standard manor: a wall/fence blocks off "the grounds" which extend a bit in front, a lesser bit to the sides, and farther out back to allow for the gardens and sheds and such. Is the house just a big rectangular prism? Are there wings? Any notable architectural features?

Do you not really know/care, and should I just ask you as it become relevant/make it up on my own as I go?

Electric, there's a "workshop" where Sara tinkers ("Creative tinker" wasn't a typo). More of a hobby than anything industrial.

It's probably not large enough to have wings, and the gardens are fairly minimal. It's pretty much an oversized townhouse with room for some staff, Sara, Sara's interests (library and workshop) and Red.

Electric lights are probably a feature, At this point I don't think the details of Sara's Manor are super important, so I'd say make it up for now, unless that bugs you. @Kadrok is welcome to add any details, of course.
